Improvement in wash-board blanks



PATENT BENJAMIN D. SANDERS, OF WELLSBURG, WEST VIRGINIA.

IMPROVEMENT IN WASH-EGARD BLANKS.

Specification forming part of Letters Patent No. 133,545, dated December3, 1872.

To all whom it may concern p Be it known that I, BENJAMIN D. SANDERS, ofWellsburg, in the county of Brooke and State of West Virginia, haveinvented a new and useful Improvementin Wash-Boards; and I do herebydeclare the following to be afull, clear, and exact description thereof,reference being had to the accompanying drawing mak ing a part of thisspecification, in which- Figure l represents a perspective view of awash-board made in accordance with my improvement; and Fig. 2 is asectional view of `the wash-plate through x, Fig. 1.

Like letters of reference indicate like parts in each.

In this washboard proper (which is made of a metallic sheet) a series ofprotuberances is swaged up or rolled up from the face of the sheet, such"protuberances being imperforate and conical in form.

To enableL others skilled in the art to make and use my improvement, Iwill proceed to describe its construction and mode of operation.

The framing b is made in any suitable form for vholding the wash-boardsheet, blank, or plate a, which latter is inserted in or fastened to theframe in any suitable way. rlhis washboard plate a is made of and in it,by stamping between suitably-faced dies, or by rolling betweenproperly-formed rolls, such asis usually employed for such purposes, aseries of protuberances, c, are made projecting upwardly on thewashing-face, in anydesired number and in any desired relativearrangement. These protuberances are made conical in form, as shown.Care should be taken that the devices which form the protuberances cshould not perforate the metal or other material or so seriously impairits ber as to render it liable to break under such use as it is put toin a laundry.

The arrangement of these protuberances which I prefer is that shown inthe drawing, where each protuberance c comes opposite to the space aboveor below, or both, which, in the row above or below, or both, intervenesbetween two protuberances in such row. Then, as the garments are rubbedup and down on the board, each part of their exposed face is operated onuniformly 5 the parts which pass between protuberances in one row areforced over them in the next, and so on alternately and continuouslywhile the work is in progress. At the same time, as the bases of theprotuberances c are in the common plane of the face of the plate a thewater is free to pass in every direction, and drain oft' as the garmentswhich are being washed approach a state of perfect cleanliness. Hencethe articles which are being washed will not take up the dirty waterpreviously given off.

What I claim as my invention, and desire to secure by Letters Patent, is

As a new article of manufacture, washboard blank having conical upliftsor projections c raised from plain surfaces of sheet zinc by compressionbetween suitably-formed dies or rolls, substantially as set forth.

In testimony whereof, I the said BENJAMIN D. SANDERS, have hereunto setmy hand.
